Fabric Strap with Multi-Layer Structure For Air-Cushion Effect And Uses Thereof In Underwear

ABSTRACT

The present utility model relates to the technical field of fabric straps, more particularly, it relates to a fabric strap with a multi-layer structure. Said fabric strap itself is integrally interwoven by the fabric with at least a double-layer structure. It is characterized in that: there are at least two layers fabric connecting up-and-down with one or more groups of yarn according to a certain weave structure. Said one or more groups of yarn not only can form an air cushion with erect fine hairs, but also can increase anti-bursting strength of the fabric. When the present utility model is applied to the shoulder straps of underwear, it can effectively relieve the stress on the skin generated by the fabric straps and increase comfort of underwear; when applied to the underwear wire casing, it can not only greatly increase anti-bursting strength, but also relieve the stress on female breasts generated by wire with formed cushion, thus preventing uncomfortable stress on the points of contact on skin after wearing said underwear. Impressions on the skin can be avoided and the comfort and safety of underwear can be improved.

This application claims benefit from U.S. Provisional Application No.61/239,463, filed Sep. 3, 2009.

FIELD OF THE INVENTION

The present utility model relates to the technical field of fabricstraps. Particularly to a new fabric strap with a multi-layer structure.

BACKGROUND OF THE INVENTION

Presently, fabric straps are widely used in the textile industry anddaily life, specifically in the garment industry. For example, fabricstraps are essential accessories for underwear. In recent years,dramatic improvements have been made in the design and appearance offabric straps. In order to make fabric straps more beautiful, patterns,decorations and color designs are changing with each passing day, yetless improvement has been made in the structure and function of fabricstraps. Taking underwear straps as an example, one sees that mostregular-sized underwear adopt narrow fabric straps as their shoulderstraps to make the appearance look more exquisite. But for developedfemales, in order to keep the figure, the underwear straps need to bearlarge amounts of tension. Narrow straps will press hardly against theshoulders, thus causing discomfort for the wearer. In addition, it iseasy for the narrow straps to generate impressions on the skin. Due tothese problems, the present method is to connect a length of softer,thicker and wider fabric strap at the shoulder position of the shoulderstrap through sewing, so as to satisfy the function required. However,it has complicated working procedures and leads to low work efficiency,which hinders automated production. Moreover, due to the presentstitching position, the fabric strap affects the integral aesthetics andcan cause skin allergies, red impressions or uncomfortable feelings,etc. due to friction. Another example is underwear wire casing. Atpresent, two types of steel casing straps for underwear are available inthe market: those that contain hot-melt yarn and those that do notcontain any hot-melt yarn. The steel casing straps without the hot-meltelement are structurally loose and prone to perforation. The steelcasing straps with hot-melt yarn in the weft, which during the dryingprocess are hot-melt and adhered to the cross-points of other yarnwithin the fabric, have an enhanced strength to effectively prevent thesteel wire from perforating. For example, U.S. Pat. No. 6,071,578discloses a tubular fabric with a hot-melt yarn, which is hot-melt toform a barrier on the inner wall of the tubular fabric to preventperforation by steel wire, yet has complicated working procedures andhigh costs. In addition, the steel casing strap for underwear has adouble-layer tubular structure with uniform thickness and would form alayer of hard film after the hot-melt yarn is heated. After theunderwear wire is embedded, it will form a hard embossment, createuncomfortable stress and generate impressions when the embossmenttouches the wearer's skin, which provides a poor level of wearingcomfort.

SUMMARY OF THE INVENTION

The utility model aims to provide a new fabric strap with a multi-layerstructure, to improve upon the limitations of present technology. Themulti-layer structure of the present utility model can form a cushionwith erect fine hairs, which can relieve the pressure on the skin causedby the fabric strap and steel casing, making the underwear morecomfortable. Meanwhile, proneness to penetration from steel wired casingcan be reduced. The steel casing with the present structure, not onlycontains no hot-melt yarn, but also has incredible anti-burstingstrength far more than the steel casing fabric containing hot-melt yarn,which can reduce the cost and simplify production process.

In order to achieve the above purpose, the utility model adopts thefollowing technical scheme: a new fabric strap with multi-layerstructure contains fabric with at a least two-layer structure. Saidfabric strap itself is the fabric with at least a two-layer structureinterwoven and connected by a group or multiple groups of yarn accordingto a certain weave structure.

Said fabric strap is formed by integral weaving.

Said fabric strap is divided into several groups according to the yarnconnected with every layer.

Said fabric strap contains at least two groups of the above connected atevery layer of yarn.

Said yarn connecting fabric of every layer form the air cushion with astructure of erect fine hairs.

The upper-layer fabric of said fabric strap is interwoven by upper-layerwefts and upper-layer warps, the middle-layer fabric is interwoven bymiddle-layer wefts and middle-layer warps while the lower-layer fabricis interwoven by lower-layer wefts and lower-layer warps.

Said upper-layer fabric, middle-layer fabric and lower-layer fabric arewoven integrally, forming the fabric strap itself with a tubularstructure.

Said fabric strap body has a folding part in the middle position and thebody of fabric strap folds and sews along the above folding part,forming a tubular structure. The middle of said tubular structure willform a wire channel used as the outer package of the wire.

Every layer of fabric of said fabric strap is a plain structure orpatterned structure.

The peripheral surface of said fabric strap itself is a napped orunnapped surface.

Said fabric strap itself can be an elastic fabric or a non-elasticfabric strap.

Below are the advantages of the present utility model:

1. The new fabric strap with multi-layer structure of said utility modelcan be interwoven to the fabric strap with air cushion by velvet loom.Said air cushion (1) is the layer with erect fine hairs formed by one ormore groups of nap warps (17) interwoven and connected with the upper-and lower-layers of fabric according to a certain weave structure. Sincethe air cushion composed of erect fine hairs are thicker and softer andalso has the effect of relieving pressure, so when said fabric strapwith air cushion of the present utility model is used as an underwearstrap, the pressure on the skin caused by the fabric strap can beeffectively relieved, thus increasing comfort of wear. In addition,since said fabric strap with air cushion for protection of the presentutility model is integrally woven, having a smooth and even surfacewithout connection points and comfortable hand feel, it can not onlyreduce processing operations, therefore improving production efficiency,but also ensure beautiful appearance of the clothing.

2. Said new fabric strap with a multi-layer structure of the presentutility model woven by velvet loom, which can form a cushion (2) byinterweaving by connecting two layers or more of fabric with a group ormore of yarn (24) in the body of the fabric strap. A wire channel (20)will be interwoven above or below the cushion. If the wire casing fabricstrap with said structure is adopted in the female underwear, nouncomfortable stress will be generated in the touching point of skinafter wearing underwear. In addition, it can avoid leaving impressionson the skin, improve comfort of underwear wear and greatly increase theanti-bursting strength of wire casing.

3. Said new fabric strap with multi-layer structure of the presentutility model can be woven into high-strength and anti-bursting fabricstrap by loom. The body of fabric strap is connected by every layer offabric with one or more groups of yarn (35) according to a certain weavestructure. By folding and sewing said new fabric straps, a tubularstructure will form. It will form a wire channel used as the outerpackage in the middle of the tubular structure, which greatly increasesthe anti-bursting strength and reduces the probability of sufferingbodily harm due to wire. In addition, it can provide a better hand feelof the wire fabric strap and improve the comfort of underwear.
